Abstract
A silver halide photographic light-sensitive material is disclosed. The material is comprised of one or more light-sensitive silver emulsion layers and one or more light-insensitive layers. The silver halide layers or light-insensitive layers contain an ultraviolet ray absorbing polymer latex. The polymer latex is comprised of a homopolymer or copolymer having a repeating unit derived from monomers represented by the following general formula (I): ##STR1## wherein the substituents within a general formula (I) are defined within the specification. The polymer latex (I) contains a substituents Q which represents an ultraviolet ray absorbing group represented by the general formula (II): ##STR2## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 each represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, an aryloxy group having 6 to 20 carbon atoms, an alkylthio group having 1 to 20 carbon atoms, an arylthio group having 6 to 20 carbon atoms, an amino group, an alkylamino group having 1 to 20 carbon atoms, an arylamino group having 6 to 20 carbon atoms, a hydro…
